  "description": "In the Linux kernel, the following vulnerability has been resolved:  net: dsa: mxl862xx: fix use-after-free of DSA ports in crc_err_work  Upon an MDIO CRC error mxl862xx_crc_err_work_fn() walks the DSA ports and closes the CPU port conduits:  \tdsa_switch_for_each_cpu_port(dp, priv-\u003Eds) \t\tdev_close(dp-\u003Econduit);  mxl862xx_remove() unregisters the switch before cancelling this work:  \tset_bit(MXL862XX_FLAG_WORK_STOPPED, \u0026priv-\u003Eflags); \tcancel_delayed_work_sync(\u0026priv-\u003Estats_work); \tdsa_unregister_switch(ds); \tmxl862xx_host_shutdown(priv);  dsa_unregister_switch() frees the dsa_port objects. If a CRC error schedules the work during teardown it can run after the ports have been freed and dereference freed memory.  Guard the port walk with MXL862XX_FLAG_WORK_STOPPED, which is already set before dsa_unregister_switch(). DSA tears the ports down under rtnl_lock(), so checking the flag under rtnl_lock() means the work either runs before teardown and sees valid ports, or runs afterwards, observes the flag and skips the walk. This mirrors the host_flood_work handler, which skips torn-down ports under rtnl_lock().",
